What happened?
According to its seller FAQ, Binance requires sellers of its stock put options product to have the full amount needed for a potential buyback locked up, specifically in USDC. The FAQ also mentions the possibility of early assignment of the option by the buyer. CryptoSlate drew attention to these details.
A put option is a contract that gives the buyer the right to sell an underlying asset at a predetermined price. The seller of a put option, by contrast, commits to buying that asset back if the buyer exercises their right. To ensure the seller meets this obligation, Binance locks up a corresponding reserve in advance, according to the FAQ.
Define: USDC is a stablecoin issued by Circle, pegged 1:1 to the US dollar.
Where is the ambiguity?
The core of the discrepancy the source points to is this: while the seller FAQ describes a mechanic that assumes a selling (short) side of the trade and full backing of the obligation, the linked trading terms still describe trading as long-only.
In other words, two documents from the same platform contradict each other. It is not clear from them which regime actually applies to users, nor whether this is a documentation error, a gradual rollout of a feature, or a product available only to some users.
What is verified and what is not?
What is verified is what stands in the documents described by CryptoSlate: the full USDC backing requirement, the mention of early assignment, and the conflict with the long-only wording of the terms.
Practically everything else around the scope of the product remains unverified: which specific stocks serve as the underlying, which jurisdictions and users the offer is available to, what the fees, expirations and limits are, and whether these are tokenized stocks or another type of contract. The available source does not state these details, which is why we do not state them either.
Why is it interesting that the backing is held specifically in USDC?
The fact that the platform ties collateral to USDC fits into a broader trend: USDC is increasingly becoming a settlement and collateral asset across both crypto and traditional finance.
During the same period, two unrelated but symptomatic pieces of news about the role of USDC appeared:
| Event | What happened | Source |
|---|---|---|
| Regulation in the EU | The EBA designated USDC as the first "significant" electronic money token (EMT) in the EU under MiCA; enhanced oversight begins on 12 November 2026, and it is dual (EBA and France's ACPR). | The Block, Incrypted |
| Payments | Visa Direct moved USDC prefunding into production via the API of provider Inyo Global. | The Defiant |
These three fragments are not directly related and do not form a single story. Together, however, they show that USDC is simultaneously taking on the role of collateral, a settlement asset in payments, and an object of heightened regulatory oversight. Note: this is not a claim that one thing causes another. It is a correlation in time, not proven causation.
What to watch out for with this type of product?
This is not advice on what to do, but a list of things that are usually worth verifying directly in the primary documents for derivative products on exchanges:
- Document consistency. If the FAQ and the terms contradict each other (as here), it is reasonable to wait for official clarification rather than rely on one of them.
- Collateral mechanics. What exactly is locked, when, and under what conditions the reserve is released or seized.
- Early assignment. Who can exercise the option and when, and what consequences this has for the other side.
- Availability by jurisdiction. Whether the product is even offered in the location where the user is.
Once Binance aligns the wording or adds an official announcement, we will update this text.
